Since people pay more and more attention to living quality, besides daily necessities, people gradually pay more attention to fun of home living. An aquarium is often placed in the house for fun. As progress of biology technology, more and more types of aquatic organisms can be fed in the aquarium. Most of fish or aquatic animals and plants can beautify the environment and are enjoyable in seeing. Therefore, there is always a proper position to place an aquarium in a drawing room or a living room.

Since a lot of aquatic animals and plants are fed in aquariums, it is important to monitor and control water quality of the aquariums for providing good living conditions to the aquatic animals and plants thereby showing the best of the aquarium. Since the aquarium forms a closed circulation system, excretion from the aquatic animals and plants or micro-organisms and bacteria in water may cause water pollution in the aquarium due to slight carelessness, which may adversely affect the living of the aquatic animals and plants even make the aquatic animals and plants dead. Therefore, it is important to have a device for detecting water quality of the aquarium.

Referring to FIG. 1 showing a schematic view of a conventional water quality detecting device, the water quality detecting device 10 includes a body 11, a cover 14, a detecting signal line 12 and a power line 13. The detecting signal line 12 and the power line 13 extend from the top of the body 11 and are coupled to a detecting control module (not shown) disposed inside the body. The connector of the detecting signal line 12 is made of metal.

The cutout 291 is in communication with the positioning slot 29 and is smaller than the positioning slot 29 thereby cooperatively forming a T-shaped mounting slot.

As shown in FIG. 3, the transparent cover 30 includes a covering board 31 coverable the front face of the casing 20, and upper and

lower sidewalls

32, 33 extending perpendicularly from the upper and lower edges of the covering board 31 and respectively covering the

circular recesses

26, 27 and the water guiding groove 28 disposed at the upper and lower faces of the casing 20. A pair of cylindrical posts 34 is disposed at inner sides of the upper and

lower sidewalls

32, 33 close one end thereof for correspondingly extending into the

circular recesses

26 or 27. Therefore, when the cylindrical posts 34 of the transparent cover 30 are respectively received in the

circular recesses

26 or 27 of the casing 20, the transparent cover 30 is rotatable about the pair of cylindrical posts 34.

Referring to FIG. 5, the seat 40 includes a flat board 41, a first insertion member 42 upwardly and slantingly extending from the center of the flat board 41, for extending into the positioning slot 29, and a second insertion member 43 disposed behind the first insertion member 42 for extending into the positioning slot 29 in a reverse direction. The second insertion member 43 is longer in length than the first insertion member 42 and has a larger elevation angle than the first insertion member 42. A plurality of
